If that means character styles or paragraph styles, you can save the document as just an Illustrator file and load it with importCharacterStyles or importParagraphStyles.

// import
var doc = app.documents[0] ;
var aiFile = new File('~/Desktop/style.ai') ;
doc.importCharacterStyles(aiFile) ;
doc.importParagraphStyles(aiFile) ;

Simply export the Illustrator file containing character styles and paragraph styles as an ai file with saveAs. It can be achieved both in ui and jsx.

Or do you mean that you have not defined them as character styles or paragraph styles, but just specified fonts, sizes, colors, etc.?
